Our newborn hearing services include OAE, AABR, and Diagnostic ABR testing to ensure early and accurate detection of hearing concerns. These safe, gentle, and non-invasive assessments help evaluate inner-ear function, hearing nerve pathways, and overall hearing ability, supporting timely diagnosis and early intervention for your baby’s healthy development.
Automated ABR (AABR) measures how sound travels from the ear to the hearing nerve and brainstem. Soft clicking sounds are delivered through earphones, while small sensors placed on the baby’s head safely record the brain’s response. This objective and highly reliable test is widely used in newborn hearing screening programs and is especially important for babies who spent time in the NICU or have risk factors for hearing loss, as it can detect neural pathway concerns such as auditory neuropathy.
Otoacoustic Emissions (OAE) is a quick, gentle, and non-invasive hearing screening that checks how well the inner ear (outer hail cells cochlea) is working. During the test, a small probe is placed in your baby’s ear canal to measure natural sound responses produced by the cochlea. A normal OAE result indicates healthy inner-ear outer hair cells function, while absent responses may suggest the need for further evaluation to better understand your baby’s hearing.
Diagnostic ABR is a comprehensive hearing evaluation performed when screening results are unclear or hearing loss is suspected. This detailed test measures hearing thresholds across different sound frequencies and helps determine the type and degree of hearing loss. The baby is usually asleep or resting quietly during the test, allowing for accurate results. Diagnostic ABR plays a vital role in early diagnosis, guiding timely intervention and hearing-aid fitting when needed.
For toddlers and young children, Visual Reinforcement Audiometry (VRA) and Play Audiometry are employed as developmentally appropriate assessment techniques. These methods are specifically designed to engage the child in the testing process, encouraging reliable behavioral responses to auditory stimuli. By incorporating interactive and child-friendly approaches, both VRA and Play Audiometry enable accurate estimation of hearing thresholds while ensuring the child remains attentive and cooperative throughout the evaluation.
